Theater owners also had the option of purchasing only the Cerwin-Vega drivers and horn cabinet blueprints, buying the wood and making the horn cabinets themselves. MCA made these changes due to the success of the system and because the shipping costs of the heavy Sensurround horns were becoming very expensive.
The Cerwin-Vega brand was split for some time across two companies; Gibson for Cerwin-Vega and CVDA Holdings for Cerwin-Vega Mobile. In both lines their products are mostly known for its woofers and subwoofers capable of delivering high sound level output with comparatively low frequency ranges using comparatively low power input, as well as the red ring commonly found on the surround of many ...
412.13 Free-reed instruments feature a reed which vibrates within a closely fitting slot (there may be an attached pipe, but it should only vibrate in sympathy with the reed, and not have an effect on the pitch - instruments of this class can be distinguished from 422.3 by the lack of finger-holes).
A horn loudspeaker is a loudspeaker or loudspeaker element which uses an acoustic horn to increase the overall efficiency of the driving element(s). A common form (right) consists of a compression driver which produces sound waves with a small metal diaphragm vibrated by an electromagnet, attached to a horn, a flaring duct to conduct the sound waves to the open air.
Paul Wilbur Klipsch (March 9, 1904 – May 5, 2002) was an American engineer and high fidelity audio pioneer, known for developing a high-efficiency folded horn loudspeaker. Unsatisfied with the sound quality of phonographs and early speaker systems, Klipsch used scientific principles to develop a corner horn speaker that sounded more lifelike ...
E-plane horn (fig. b) – A sectoral horn flared in the direction of the electric or E-field in the waveguide. H-plane horn (fig. c) – A sectoral horn flared in the direction of the magnetic or H-field in the waveguide. Conical horn (fig. d) – A horn in the shape of a cone, with a circular cross section. They are used with cylindrical ...
There are many ways in which the duct can be folded and the line is often tapered in cross section to avoid parallel internal surfaces that encourage standing waves. Depending upon the drive unit and quantity – and various physical properties – of absorbent material, the amount of taper will be adjusted during the design process to tune the ...
An acoustic horn or waveguide is a tapered sound guide designed to provide an acoustic impedance match between a sound source and free air. This has the effect of maximizing the efficiency with which sound waves from the particular source are transferred to the air. Conversely, a horn can be used at the receiving end to optimize the transfer of ...
